Background. Sugammadex is a new reversal agent that has entered use recently. It is known that with sugammadex some changes in coagulation parameters occur without documented clinical results. Aim of the Work. The objective of this study was to identify effects of sugammadex on liver functions, coagulation, and fibrinolytic systems. Methods. Thirty-six rats were randomized into six groups: Group I, control; Group II, rocuronium group; Group III, sugammadex administered in 16 mg kg −1 dose; Group IV, sugammadex administered in 96 mg kg −1 dose; Group V, rocuronium and sugammadex administered in 16 mg kg −1 dose; and Group VI, rocuronium and sugammadex administered in 96 mg kg −1 dose. After 120 minutes, blood samples were obtained for prothrombin time, activated partial thromboplastin time, D-dimer, fibrinogen, aspartate aminotransferase, alanine aminotransferase, albumin, platelet, and mean platelet volume analyses. Results. Compared to the control group, in all groups measured parameters did not show any effect from a statistical viewpoint either due to the administered drugs alone or due to interaction effects. Conclusion. The conclusion was reached that administration of sugammadex in rats did not have any significant effect on the fibrinolytic system, coagulation parameters, and liver function.
